这是我的杰森回应的例子(图片和缩略图字段是blob)

{"id":"2","user_id":"1","name":"testing","type":"bouldering","picture":null,"lat":"36","long":"81","alt":"41932","accuracy":"53","thumbnail":null}

这是我的PHP脚本来返回数据.

<?PHP
require_once('config.PHP');

$MysqLi = new MysqLi(DB_HOST,DB_USER,DB_PASSWORD,DB_NAME);
$sql = 'select * from spot_main';
$results =$MysqLi->query($sql);

$spots = array();  //array to parse jason from

while($spot = $results->fetch_assoc()){
    $spots[] = $spot;                                                           
}

echo json_encode($spots);
?>

任何人知道这个问题的解决方案？我知道我不是最有效的方法(更好的存储在文件系统中的图像),但我需要这个工作.
